Hi,

in today’s publiccloud-sig meeting we’ve continued the topic of “flavor discoverability”,
a topic that has been part of our discussion for a while. Before I dive into that, a quick heads-up:

So far we’ve been meeting in the odd weeks. We’ll be switching that to the even weeks.
This means, we’ll be meeting again next week (Nov. 29th).

For today’s meeting:

The minutes for the meeting are here:
https://etherpad.opendev.org/p/publiccloud-sig-meeting

Since this was a videocall (and as such no meetingbot logs), here a quick summary (thanks @joek-office).

=======
0. Discussion on flavor/image/volume "search engine" aka flavor-discovery

• (gtema) The most informations that can be interessting for clients to search resources are at the respective services (nova/glance/cinder) in place
• nova has traits but this is not searchable (possible extension - nova mentioned this as a tricky development), especially for clients
• the traits has the ability to give out internal informations about the infrastructure, so cloud provider's possibly not happy with this solution
• (gtema) problems with finding the right flavor/image in a openstack cloud
• The flavor definitions are more or less a range in that nova scheduler will do its best to meet the criteria, no guarantee to get what you want @gtema pls update/delete this
• The architecture of the instance is more defined by the image than from the flavor
• thats because in the image are the appropriate sources for a cpu architecture
• at the moment two possible ideas

idea 1:
extend the services with the appropriate features to meet the requirements
cons:

• long development

pros:

• no moderation/weighting of results possible

idea 2:
build up a new service with required metadata based on the .wellknown concept supported by sdk right now (or discoverable via service catalogue - that's not in scope of the service catalog, but the new "discovery" service may be added into the catalog)
cons:

pros:

• the service can moderate/weight results to meet criterias from cloud provider AND client side
• available for older OpenStack versions

=========

For people interested in this subject, we (at least gtema and me) are going to continue this discussion tomorrow
at 1400 CET here: https://conf.scs.koeln:8443/OIF-public-cloud-sig
